Mike - wasn't yours a special color? anniversary or something?
there's a real low mile original '59
in the gallery, the one mirror appears to be white .... in Gunnells' book, there's one picture that appears factory of a '59 with a black mirror, a couple nicely restored others with black mirrors
it seems that from the factory, the standard single mirror could have been white like the rest of the standard trim [actually called Arctic Beige] - mirrors obtained from the dealer would have been black, like most replacement parts
and TxBill, I don't think there was a year when bumpers were black from the factory, always the Arctic Beige or chrome
